The DIWA.5 transmission reduces wear and tear through streamlined gear shifts, according to a news release from Voith. It also features gear technology designed to ensure fuel-friendly engine speeds in all levels of traffic. Since 2003, Voith has provided about 250 transmissions in buses for the transit authority.

The transmissions are being delivered to New Flyer now, and the buses are expected to be in service by the fall, Voith said.

"The transmissions are manufactured in Germany," said Voith spokeswoman Erika Winemiller. "We would service them here (in York County) when the time comes that they need to be serviced/rebuilt."

Winemiller said Voith could not disclose the terms of the deal with New Flyer.

Last month, Voith said it was providing 60 DIWA.5 transmissions for buses bound for the Port Authority of Allegheny County, which operates a bus system in Pittsburgh.
